GPS test setup
Usage
# replaying a static location
./gpstest.sh -e <ephemeris file> -s <static location>
# replaying a prerecorded route (NMEA cvs file)
./gpstest.sh -e <ephemeris file> -d <dynamic location>
If -e is not provided the latest ephemeris file will be downloaded from
https://cddis.nasa.gov/archive/gnss/data/daily/20xx/brdc/.
(TODO: add auto downloader)
Hardware Setup
- LimeSDR USB
- Asus AX58BT antenna
Software Setup
- https://github.com/myriadrf/LimeSuite To communicate with LimeSDR the LimeSuite is needed it abstracts the direct communication. It also contains examples for a quick start.
The latest stable version (22.09) does not have the corresponding firmware download available at https://downloads.myriadrf.org/project/limesuite. Therefore version 20.10 was chosen.
- https://github.com/osqzss/LimeGPS Built on top of LimeSuite (libLimeSuite.so.20.10-1), generates the GPS signal.
./LimeGPS -e <ephemeris file> -l <location coordinates>
# Example
./LimeGPS -e /pathTo/brdc2660.22n -l 47.202028,15.740394,100
